The 5,100 sq. m. facility - which cost more than €65 million to set up - will produce cell culture-based therapeutic proteins and will support UCB's biologics development activities in the research and clinical trial phases. The four bioreactors at the pilot facility have a total capacity of 3,200 litres and the unit is currently being validated alongside regulatory authorities. It is expected to become fully operational during 2013, when it will employ around 100 workers, and has been supported by the regional Walloon government.
